Highly luminescent CsPbBr3 nanorods synthesized by a ligand-regulated reaction at the water–oil interface

Abstract

For the first time we report highly luminescent CsPbBr₃ nanorods (NRs) with aspect ratios around 2–10 through chemical transformation from Cs₄PbBr₆ nanocrystals. Detailed structural characterization shows that the NRs are cubic phase with uniform growth direction. The NRs are formed through an oriented-attachment mechanism assisted by the ligand-regulation at the water–oil interface.
